Abstract: A vacuum hose storage system includes a housing which is mounted in a storage area of a dwelling or vehicle and connected to a vacuum source. A length of flexible, expandable cleaning hose is mounted in a looped fashion about a plurality of spaced rollers rotatably mounted within the housing. A handle is attached to one end of the hose and is seated in a cradle formed in the housing when the hose is in a fully retracted position within the housing. The cradle is mounted in the housing and receives the open end of the hose when not in use and enables other vacuum tubes in the structure to be operational without shutting off the vacuum to the stored hose. An ON/OFF  switch is located in the cradle for controlling the vacuum source and is actuated when the handle is placed in or removed from the cradle. The hose has an internal helical spring which biases the hose toward a retracted position about the spaced rollers within the housing.  In an alternate embodiment, the hose is slidably extendable from within a rigid serpentine tubing mounting within the housing.

Abstract: Spacecraft electric regenerator is a power regenerative device to generate electrical power to spacecrafts. The device generates its own power by rotating a rotor disc with magnetic Pole pieces attached to its inner bore around an armature coil assembly fixed to a stationary shaft The rotor disc being rotated to a predetermined velocity by a rotor mechanism and the rotation thereafter being maintained under a zero gravity and a vacuum condition due to the accumulated kinetic energy. To overcome any inherent and imposed retarding forces, the rotation being assisted by transferring the rotational power of an electric driver motor as magnetic power from a driver disc with magnetic Pole pieces attached to the outer circumference surface of the rotor disc with magnetic Pole pieces attached. The rotation being controlled by a power control and conversion process.

Abstract: Method and apparatus of separating an oxygen and nitrogen containing feed stream, for example, air, in higher and lower pressure columns. A crude liquid oxygen stream condenses nitrogen vapor in the higher pressure column for reflux purposes and results in the partial vaporization of the crude liquid oxygen stream to produce vapor and liquid fractions thereof. The liquid fraction condenses a lower pressure part of the feed stream and results in the liquid fraction being at least partially vaporized.  Both the vapor fraction of the crude liquid oxygen stream and the liquid fraction after having been at least partially vaporized are introduced into the lower pressure column. Boil-up is produced within a bottom region of the lower pressure column by partially vaporizing an oxygen-rich liquid column bottoms against condensing a higher pressure part of the feed stream and then utilizing vapor or residual liquid as an oxygen product.

Title: Arrangement to compensate a non-uniform air gap of an electric machine
Inventor: STIESDAL HENRIK
IPC: H02K1/06
Filed: 2010-12-06
Abstract: The invention relates to an arrangement to compensate a non-uniform air gap, which is located in an electric machine. The invention especially relates to a compensation of an air-gap, which is between a rotor and a stator of a generator. According to the invention the electrical machine contains a stator arrangement (108) and a rotor arrangement (114). The rotor arrangement (114) rotates around a longitudinal axis (A). At least parts (118) of the rotor arrangement interact with parts (111) of the stator arrangement to generate electrical power. The air gap is defined by the distance between the parts of the rotor arrangement and the parts of the stator arrangement. The parts of the stator arrangement are opposite to the parts of the rotor arrangement along a certain length. The cross section of the air gap changes along this length thus the air gap is not uniform in view to the referred certain length. The flux density of magnets, which are part of the rotor arrangement, is changed in dependency to the cross section of the air-gap.

Abstract: Selective insect neonicotinoids is a class of pesticide active ingredients that share some characteristics in their chemical structures and bind to the nAChR acetylcholine receptors. Formulation of such compounds in oil suspension or oil dis-persion is challenging due to their electrostatic interactions of the heteroatoms in oily media, that lead to irreversible flocculation or diminished homogeneicity and bleeding of such oil dispersions.  Imidacloprid, Thiamethoxam, Thiachloprid, Nitenpyram, Ac-etamiprid, Clothianidin and Dinetofuran and derivatives thereof with nAChR  binding ability are successfully formulated in oil suspension with the use of certain copolymeric anionic fatty-acid based dispersants, sorbitan derivatives, ionic surfactants, other non-ionic surfactants and inorganic polyvalent cationic salt dispersed in the oil. The formulations this way produced show excel-lent storage stability properties regarding physiochemical parameters, including stability of the neonicotinoid active ingredient, re-duced bleeding, and complete redispersibility. Further, they show excellent biological efficacy due to the reduced and homoge-neous particle size below 2 µm when diluted -emulsified- in water.
